CAR-C'OUPLING.

SPECIFICATION forming part of Letters Patent No. 259,129, dated June 6, 1882.

Application led March 27, 1882.

To all whom it may concern Be it known that I, JOHN B. GLEAsoN, of Dayton, in the county y of Montgomery and State of Ohio, have invented a new and Improved Oar-Coupling, of which the following is a full, clear, and exact description.

My invention relates to the hook-headed kind of car-couplings; and it consists of certain improvements in the arrangement of the hook and means for operating it, all as hereinafter described.

Reference is to be had to the accompanying drawings, forming part of this specication, in which similar letters of reference indicate corresponding parts in all the iigures.

Figure lis aplan view of the said improved car-coupling, with the platform of the car in- Fig. 2 is a side elevation, and Fig. 3 is a horizontal section.

A represents the draw-bar, of the kind commonly used, to which I apply a hook-headed catch, B, formed of the two parts Uand V, of cast-iron, secured between the two partsW W, of wrought-iron, which hook is pivoted on a pin, O, between the two checks a of the drawbar, the said catch being considerably widened in the rear end, and said end having aconcavity, D, with rounded projections E F at the corners.

Behind the said concave rear end isla sliding block, G,with its front end fitted to the concavity of the hook, and fitted to slide forward and backward between the ehocks of the draw-bar, being guided and maintained in po sition by the projections H of its sides in the slots I of the draw-bar. Behind this sliding block 1s a strong spring, J, supported against the block K, permanently fixed behind it in the draw-bar, and pressing the sliding block against the concave end of the hook B, or the corner E thereof, when the hook is open. The spring is secured in position by sockets in the blocks, into which the ends are entered.

There is a coneavity, L, into which the corner E of the hook is engaged to hold the hook open, as in the position shown in Fig. 3.

The hook has a staple or eyebolt, M, in the back, near the head, in which an elbow-lever, N, engages to open and close the hook, the said lever being pivoted at O under the plat- (Model.)

notched or forked to receive the end of a conmeeting-rod, Q, pivoted to it, and extending back and under the platform to the lever R, having a fulcrum at S to work the hook from the other side of the car. The lever R can be extended across under the car, as shown in dotted lines, Fig. 3, to couple and uncouple the ear from either side by this device, thereby,

T represents a pin in the head of the drawbar to prevent the hook from swinging open too far.

It will'be seen that byremoving the coupling-hook of the ordinary Miller coupler and punching the holes for the pin C the hooks of this improved arrangement can be applied to the draw-bar of that construction; also,that in case the hooks may become damaged they can used instead.

This arrangement has the advantage of being worked from either side 0f the car, and also from the ground, and enables the drawbar and hook-coupler to be applied to freightcars. The ordinary or other applied contrivances may be used for workin g the hooks from the platform.

prevent it from uncoupling when the draft slackens up; also to hold it in the open position. Its use enables this form of hook to be arranged on a pivot, in the place of the ordinary coupling-bolt, with the spring located in Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is y l. The combination, with the draw-head A and the sliding block G, having'eonvex forward end, of the coupling-hook B, having the concave rear end, D, substantially as and for the purpose set forth.

2. The coupling-hook B, pivoted between the ehocks of the draw-bar at C, and having concave rear end, D, and projection E, in combinaif desired, dispensing with the elbow-lever N. i

The corner F of the rear end of the hook is be taken out and an ordinary coupling-link g The function of the block G is to hold the hook securely in position when coupled, and

the draw-bar behind it. Y

The combination of hook-coupler B, pivoted on the draw-bar, as described, and having projections E and F, sliding block G, spring md levers O and Q, substantially as speciend, and being arranged between the chocks of the draw-bar, with projections H in guideslots I of the said bar, in combination With hook B, substantially as specified.

6. The combination of stop-pin T with the 2o hook B, pressure-block G, draw-bar A, and the lever N, substantially as specified.
